Energy crisis and shrinking of the habitable environment are the two harsh realities staring at our eyes today. One of the factors contributing to this is the almost exclusive dependence on fossil fuels for all of our daily activities ranging from industries, automobiles, and even household work. These non-renewable resources, which are not replenished quickly, are getting depleted at an alarming rate as their demand is consistently escalating. And the time when these fossil fuels will become too expensive to be used by common people, is not very distant. The majority of the fuel sources like petroleum products and coal are also potential pollutants. A few hundred years of imprudent use of fossil fuels by us, and the effects have already started to show up – dwindling fossil fuel reserves, climate change, rising global temperatures and melting polar ice caps.
When the first laser was invented in 1960, it was described as a “solution looking for a problem.” Interestingly, lasers these days have revolutionized our society. They have found widespread use in science, technology and medicine. Now, scientists at the Indian Institute of Science (IISc), Bangalore, have designed a new laser material which will not only transform, but also ease the development of next-gen powerful lasers.
A camera helps us capture a moment and relive the moment at a later time. Although cameras have been getting faster and more efficient, the cost has also gone up at the same time because of the technologies involved. A team at IISc have recently fabricated a novel kind of imaging sensor that could lead to faster and economical cameras.
Dr.Satish Patil is the principal investigator at the Organic Electronics Group in the Indian Institute of Science. Within the vast universe of Chemistry, he finds his niche in the world of macromolecules, specifically, conjugated polymers. Dr. Patil studies and synthesizes these large organic molecules with a view to incorporate them into electrical, optical and various other devices that the world is dependent upon. Driven by the need to impact society, his research is increasing the momentum of a wave that is moving towards a more efficient and affordable energy.
We sometimes hear of post-surgery infections, which can even result in untimely death. A single efficient drug with the potential to combat the sudden and rapid spread of sepsis in the intensive care units of hospitals has been developed.
A research effort led by Bharata Ratna Prof C N R Rao may lead to a cost effective way of producing synthetic gas. Prof C N R Rao and his team have found an efficient way to generate hydrogen and carbon monoxide, using lanthanum calcium manganate. This material not only produces larger amounts of hydrogen and carbon monoxide, but achieves it at a relatively lower temperature range.
Researchers from the Indian Institute of Science have developed a device that could lead to better batteries. The devices, called the ‘supercapacitor’, can store a lot of charge, be charged/discharged quickly and withstand many charge/discharge cycles. More work is needed to make it ready for the market, but the basic design is ready.
